If action potentials follow the all-or-none principle how is it possible for us to distinguish between different levels of stimulus intensity?
A) The number of neurons affected codes for stimulus intensity.
B) The rate at which the cell fires codes for stimulus intensity.
C) Various neurons transmit neural impulses at different speeds.
D) Both b and c.

Question

Quizplus · Accepted Answer

The rate at which action potentials are fired (option B) can be used to distinguish between different levels of stimulus intensity. Additionally, different neurons may transmit signals at different speeds (option C), which can also help the brain distinguish between different levels of stimuli. Therefore, both options B and C are correct.
